Description

Technical Field

[0001] This utility model relates to the field of concrete pouring, specifically a concrete pouring pump pipe control device to prevent spillage. Background Technology

[0002] During concrete pouring, when moving from one location to another, even though the pouring pump is paused, residual concrete slurry will still flow from the pump pipe. Moving the pump pipe at this time will cause the slurry to spill onto the surrounding building structure, easily resulting in different grades of concrete spilling onto the roof beams and forming slabs, affecting the acceptance and aesthetics of the building structure. Current practices generally involve using woven bags to seal the end of the pump pipe, or waiting until all the slurry has flowed out before moving the pipe. However, these methods are not very secure and can easily lead to the pump pipe end solidifying and clogging over time, affecting subsequent pouring. Furthermore, the waiting time is long, affecting the overall pouring efficiency. Therefore, how to prevent concrete slurry from spilling onto surrounding buildings when moving the pouring location is a major challenge in concrete pouring construction. Utility Model Content

[0003] The purpose of this utility model is to provide a concrete pouring pump pipe control device to prevent spillage. It can solve the technical problem that the grout is easily spilled when the concrete pouring position is changed, which affects the acceptance and construction quality. It can realize the effective opening and closing control of the grout at the end of the pump pipe, prevent grout leakage or solidification and blockage, ensure smooth subsequent pouring, and improve the efficiency of concrete pouring construction.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] A concrete pouring pump pipe control device to prevent spillage includes a pouring seat sleeved on the outside of the pump pipe end. The pouring seat has a temporary storage cavity inside, and an inclined guide slope is provided inside the temporary storage cavity. A discharge pipe is provided on one side of the pouring seat at the bottom end of the inclined direction of the guide slope. The discharge pipe is provided with an opening and closing component to control its opening and closing. An installation sleeve is provided on the top of the pouring seat and is sleeved on the outside of the pump pipe end. A slidable rod is vertically connected to the bottom of the pouring seat. A slidable seat is provided on the top of the slidable rod inside the temporary storage cavity. The slidable seat is located below the installation sleeve.

[0006] Furthermore, the opening and closing assembly includes a rotating shaft rotatably connected to the discharge pipe, a partition plate at the bottom of the rotating shaft, the partition plate being rotatably connected inside the discharge pipe, the longitudinal cross-sectional shape of the partition plate being adapted to the longitudinal cross-sectional shape of the discharge pipe, and a rotating seat at the top of the rotating shaft.

[0007] Furthermore, slide blocks are symmetrically connected vertically on both sides of the rotating seat, and a compression spring is provided between the slide blocks and the rotating seat. A limiting plate is provided on the discharge pipe, and multiple limiting holes are provided on the limiting plate. A limiting block that cooperates with the limiting holes is provided at the bottom of the slide block.

[0008] Furthermore, the limiting plate has a circular cross-section, the limiting hole is a plurality of toothed grooves formed on the edge of the limiting plate, and the limiting block is a limiting tooth that cooperates with the toothed grooves.

[0009] Furthermore, the mounting sleeve is provided with clamps for fixing the pump pipe, and multiple reinforcing ribs are symmetrically provided on both sides of the mounting sleeve and between the casting base, and multiple support seats are provided at the bottom of the casting base.

[0010] Furthermore, the unblocking seat includes multiple unblocking strips arranged in a circular array.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. The structure of this utility model has a pouring seat sleeved on the outer side of the pump pipe end, and a temporary storage cavity inside the pouring seat. An inclined guide slope is set in the temporary storage cavity, and a discharge pipe is set on one side of the inclined direction of the guide slope. An opening and closing component is set on the discharge pipe to control its opening and closing. When the position needs to be moved after pouring, the opening and closing component is used to close the discharge pipe, so that the concrete slurry flows into the temporary storage cavity for temporary storage. The setting of the temporary storage cavity can effectively store the slurry and prevent it from spilling onto the surrounding buildings. Moreover, the larger volume of the temporary storage cavity relative to the pump pipe can effectively prevent the slurry from solidifying and clogging the pump pipe. It realizes effective opening and closing control of the slurry in the pump pipe. When the pump pipe is moved to a new position for pouring, the opening and closing component is used to open the discharge pipe, and the slurry in the pump pipe is smoothly discharged from the discharge pipe along the guide slope, ensuring the smoothness of concrete pouring and effectively preventing the spillage of concrete slurry during the change of pouring position, thus ensuring the quality and efficiency of concrete pouring construction.

[0013] 2. The top of the pouring base is equipped with an installation sleeve for connecting to the pump pipe, making the connection between them more convenient. The bottom of the pouring base is vertically connected to a dredging rod. When the pump pipe is obstructed, the dredging rod is slid up and down, allowing the dredging seat at the top of the dredging rod to enter the pump pipe for dredging. This effectively dredges the pump pipe without removing the pouring base, further improving the smoothness and efficiency of the pouring construction. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0023] Reference Figure 1 and Figure 2This utility model describes a concrete pouring pump pipe control device to prevent spillage. The main structure includes a pouring seat 1 sleeved on the outside of the pump pipe end. The pouring seat 1 is generally made of wood or metal. The pouring seat 1 has a temporary storage chamber 2 inside, which is connected to the pump pipe. The temporary storage chamber 2 has an inclined guide slope 3 located below the pump pipe. A discharge pipe 4 is connected to one side of the pouring seat 1 at the bottom of the inclined guide slope 3. This structure allows the concrete slurry entering the temporary storage chamber 2 from the pump pipe to automatically flow along the inclined guide slope 3 to the discharge pipe 4, thus making the concrete pouring smoother. The discharge pipe 4 is equipped with an opening and closing component to control its opening and closing. This component can close the discharge pipe 4 when the pouring position is changed, thus temporarily storing the concrete slurry in the temporary storage chamber 2. The temporary storage chamber 2 has a larger internal volume than the pump pipe. The larger surface area makes it less prone to clogging, thus preventing grout spillage and ensuring the smoothness of subsequent pouring. This effectively reduces the potential contamination of the top slab beam by the grout, ensuring the quality and efficiency of the pouring construction. The top of the pouring seat 1 is welded or integrally formed with an installation sleeve 5, which is fitted onto the outside of the pump pipe end, making the connection between the pouring seat 1 and the pump pipe more convenient and secure. The bottom of the pouring seat 1 is vertically slidably connected with a dredging rod 6, one end of which passes through the pouring seat 1 and extends into the interior of the temporary storage cavity 2. The top of the dredging rod 6, located inside the temporary storage cavity 2, is fixed with a dredging seat 7 by welding or integral forming. The dredging seat 7 is located below the installation sleeve 5. This structure allows the dredging rod 6 to slide up and down without disassembling the pouring seat 1, enabling the top dredging seat 7 to penetrate into the pump pipe for dredging, further ensuring the smoothness of subsequent pouring construction.

[0024] Preferred, refer to Figure 3 The opening and closing assembly includes a rotating shaft 8 rotatably connected to the discharge pipe 4. A partition plate 9 is fixed to the bottom of the rotating shaft 8 by welding or integral molding. The partition plate 9 is rotatably connected to the inside of the discharge pipe 4. The longitudinal cross-sectional shape of the partition plate 9 is adapted to the longitudinal cross-sectional shape of the discharge pipe 4. A rotating seat 10 is provided at the top of the rotating shaft 8. With this structure, the partition plate 9 can be driven to rotate inside the discharge pipe 4 by rotating the rotating seat 10 from the outside, so that the partition plate 9 is parallel or perpendicular to the axial direction of the discharge pipe 4, thereby closing or opening the discharge pipe 4. The structure is simple and the opening and closing control of the discharge pipe 4 is more accurate and convenient.

[0025] Preferred, refer to Figure 4 and Figure 5The rotating seat 10 has symmetrical vertical sliding connections to two slide seats 11 on both sides. A compression spring 19 is provided between the slide seats 11 and the rotating seat 10. A limit plate 12 is fixed to the discharge pipe 4 by welding or bolts. The limit plate 12 has multiple limit holes. The bottom of the slide seat 11 has a limit block that cooperates with the limit holes. This structure allows the slide seats 11 on both sides to slide upward when the rotating seat 10 rotates, so that the limit block at the bottom of the slide seat 11 disengages from the limit hole. After rotating to the correct position, the slide seat 11 is released, and under the action of the compression spring 19, the limit block at the bottom of the slide seat 11 automatically enters the limit hole, thereby effectively fixing the position of the rotating seat 10. This keeps the partition plate 9 connected to the rotating seat 10 in the rotated state, thus maintaining the opening and closing state of the discharge pipe 4, making the opening and closing control of the discharge pipe 4 more accurate and stable.

[0026] Preferred, refer to Figure 6 The limiting plate 12 has a circular cross-section, the limiting hole is a plurality of toothed grooves 13 formed on the edge of the limiting plate 12, and the limiting block is a limiting tooth 14 used in conjunction with the toothed grooves 13. This structure makes the engagement between the limiting tooth 14 and the toothed grooves 13 more secure and accurate, thereby further improving the limiting effect on the limiting seat.

[0027] Preferably, the mounting sleeve 5 is provided with clamps 15 for fixing the pump pipe, so that the pump pipe can be quickly clamped and fixed after being inserted into the mounting sleeve 5, which further simplifies the connection steps and improves the efficiency and convenience of the connection operation. Multiple reinforcing ribs 16 are symmetrically fixed to the two sides of the mounting sleeve 5 and the pouring seat 1 by welding or integral molding, which can improve the firmness of the mounting sleeve 5, prevent the pump pipe from shaking or bending relative to the pouring seat 1, and ensure the smoothness of the pouring. Multiple support seats 17 are fixed to the bottom of the pouring seat 1 by welding or bolts to ensure the flatness of the pouring seat 1 and improve the stability of the pouring process.

[0028] Preferably, the unblocking seat 7 includes a plurality of unblocking strips 18 arranged in a circular array. The array arrangement of the plurality of unblocking strips 18 creates gaps between them, thereby reducing the contact area and increasing the unblocking force when unblocking deep into the pump pipe. Furthermore, the spaced unblocking strips 18 can break up the blocked concrete, further improving the unblocking effect.

[0029] Working Principle: This invention features a pouring seat 1 fitted onto the outer side of the pump pipe end. Inside the pouring seat 1 is a temporary storage chamber 2, within which is an inclined guide slope 3. A discharge pipe 4 is located on one side of the inclined direction of the guide slope 3. An opening and closing assembly is installed on the discharge pipe 4 to control its flow. When the pumping is completed and the pump needs to be moved, the opening and closing assembly closes the discharge pipe 4, allowing the concrete slurry to flow into the temporary storage chamber 2 for temporary storage. The temporary storage chamber 2 effectively stores the slurry, preventing it from spilling onto surrounding buildings. Furthermore, the larger volume of the temporary storage chamber 2 relative to the pump pipe effectively prevents the slurry from solidifying and clogging the pump pipe. This achieves effective opening and closing control of the slurry within the pump pipe, allowing the pump pipe to be moved to a new location for pouring. When the discharge pipe 4 is opened using the opening and closing component, the slurry in the pump pipe is smoothly discharged from the discharge pipe 4 along the guide slope 3, ensuring the smoothness of concrete pouring and effectively preventing the spillage of concrete slurry during the change of pouring position, thus ensuring the quality and efficiency of concrete pouring construction. The top of the pouring seat 1 is equipped with an installation sleeve 5, which is used to connect with the pump pipe, making the cooperation between them more convenient. The bottom of the pouring seat 1 is vertically connected to a dredging rod 6. When the pump pipe discharge is not smooth, the dredging rod 6 is slid up and down, allowing the dredging seat 7 at the top of the dredging rod 6 to enter the pump pipe for dredging. The pump pipe is effectively dredged without removing the pouring seat 1, further improving the smoothness and efficiency of the pouring construction.
